Mac 35 series are the go to solenoid valve for automotive boost control due to their exceptionally rugged and reliable design. What that means is that the solenoid has 3 ports of entryexit available.
Boost Control Systems Explained Part 3 Perrin Performance
3 port boost solenoid explained. As supplied with gfb electronic boost controllers g force ii 3004 g force iii 3005 and d force 3006 3007. In a turbocharged vehicle there are a couple components that make up the boost control system. It controls boost pressure. Many upgrades to the turbocharging system big turbos and ewg require the increased performance reliability flexibility safety and installation options that the full race 3 port bcs provides. Boost enters the solenoid and passes through to the wastegate actuator when the solenoid is turned off. This is how almost all modern boost control works.
Full races 3 port boost control solenoid bcs adds the flexibility and precision needed for properly controlling boost via the factory ecu. Its works like this. With the 3 port bcs the tuner can adjust how much boost you get at given point. The perrin ebcs pro electronic boost control solenoid utilizes 3 ports to control boost which can be setup in many ways other than the stock bleeding type system. Those ports can move fluids in or out of the solenoid based on what youre looking to accomplish. The wastegate and the boost controller.
3 port boost control solenoid. When the solenoid is actuated 100 of the time it results in the highest boost the system can run 100 wgdc. Supposedly its safer it is definitely not safer on its own. The important thing to remember is that 0 wastegate duty cycle 0 wgdc means the solenoid is not being actuated at all and this results in low boost spring pressure. No surprise there. When the solenoid is turned on by the ecu it blocks boost pressure from getting to wastegate actuator and at the same time relieves any pressure built up in the line going to the actuator.
Safer here is very subjective as a mbc can be run safely however keep in mind that a mbc will always aim for its set psi target. This allows for better boost control quicker response and more boost from your turbo. The 3 port ebcs is a solenoid that does just what the name implies. A 3 port electronic boost controller is a controller that has 3 ports on it.
